If the transfers already are slow using rclone, have you considered just mounting the directories you are using on the Hetzner to your local computer and just downloading the torrents directly to the mounted directories? It would stop using space on your local machine but you would still get to interface with the files like they were local. Also like you said the transfer speed is slow already so its shouldn’t be much of a hit on your speed or it might even make it better depending on how rclone is handling things. I’m not to familiar with rclone so I can say much about it.
